| Heamoglobin is [[iron|iron]] containing compund that binds to [[oxygen|oxygen]] gas. It is found in the [[Red_blood_cells|red blood cells]] of vertebrates. It transports oxygen from the respiratory organ, the [[lungs|lungs]], to the different cells of body. It is a [[protein|protein]] that contains a quanternary structure made up of 4 sub-units. They consist of 2 alpha sub units and 2 beta subunits. Each subunit conatins a haeme group which contains and iron [[atom|atom]]. Each iron atom binds to 1 oxygen molecule. Thus 1 haemogobin molecule transports 8 atoms of oxygen. When absorbtion of oxygen occurs haemoglobin becomes [[oxyheamoglobin|oxyheamoglobin]] and it forms the reddish colour of the red blood cells. Upon arrival at a cell it deposits its oxygen thus allowing oxidization of glucose to take place via respiration. This releases energy in form of ATP. The waste product, [[Carbon_dioxide|carbon dioxide]] is transported by heamoglobin to the lungs for expiration <ref>Berg, J. Stryer, L. Tymoczko J. (2012) Biochemistry, 7th Edition : W.H. Freeman and Company. Chapter 7, Page 203-207</ref>.
